a small 5.00 kg rocket burns fuel that exerts a time-varying upward force on the rocket (assume constant mass) as the rocket moves upward from the launch pad. This force obeys the equation F = A + Bt^2. Measurements show that at t = 0, the force is 130.0 N, and at the end of the first 2.00 s, it is 152.0 N. (a) Find the constants A and B, including their SI units. (b) Find the next force on this rocket and its acceleration (i) the instant after the fuel ignites and (ii) 3.50 s after the fuel ignites. (c) Suppose that you were using this rocket in outer space, far from all gravity. What would its acceleration be 3.50 s after fuel ignition?

Explanation:

A small 8.00 kg rocket burns fuel that exerts a time varying upward force on the rocket A small 8.00-kg rocket burns fuel that exerts a time- varying upward force on the rocket (assume constant mass) as the rocket moves upward from the launch pad. This force obeys the equation F = A + Bt2. Measurements show that at t = 0, the force is 100.0 N, and at the end of the first 2.00 s, it is 150.0 N.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
